Improvement in corn-harvesters

IMPROVEMENT IN CAORNHARVESTERSv Specification forming part of Letters Patent No. 14,730. dated April 22, 1856.

To all whom it may concern.-

Be it known that we, It. C. MAUOK and 7. T. MCGAHEY, the former of Gonrads Store and the latter of McGaheysville, Rockingham county, Virginia, have invented a new and useful Improvement in Oorn-Harvesters; and

we do hereby declare that the following is a receiver, and cut the stump near the surface ot' the ground.

The invention' consists in constructing in front of the machine a double series of cutters, operated from the rotation of one ot' the wheels for the purpose of cutting the stalk and removing the stumps, and in constructing above the upper cutters frames oscillated by the vibration ot' said cutters for throwing the cut stalk across the machine upon an inclined guide leadingto the body of the machine, where radial arms of the main shaft seize the stalk and force it under packing-guides to the rear of the body, theA details of construction and operation being as follows: t

In the drawings, A is the body of the machine, supported so as to run close to the surface of the ground upon the main axle B, upon which are the wheels G C.

ln front of the machine are the two series of cutters, a and 1), operated simultaneously from the rotation ot' the wheel O by the alternate action of the pins c upon the opposite inclined planes, d d', connected with the cutterbars, yor by any of the usual methods ot' producing the reciprocation of the cutter-bar from the rotation of the driving-wheel. The upper cutters, (t, which are the ordinary triangular cutters, vibrate beneath and in contact with the stalkireceivers j', whose edges c are sharpened, so that a shear cutis made between them and cutters a. IVe do not design, however, to restrict ourselves to this construction ot'cutter. The lower cut-ters, b, are also triangular, and by their reciprocation sever the stumps with which they come in contact.

Hinged upon the upper edges of the projecting side pieces, g, are the frames h h, connected by the rod t', and oscillated laterally by reason of connection Z with bar m of cutters.

Extending obliquely forward from the front of the body is the guide n, which submits the stalk to the arms of the main shaft B.

The front of the body has a curved interior, o, so that arms jp of the shaft will carry the stalk under the packing-guides q, whence it is' forced to the rear of the body, as will be set forth.

The wheel O is placed loosely upon the shaft, and has a ratchet-and-pawl connection, r, so that in backing the wheel C will turn loosely, and not act on the shaft.

The operation of the harvester is as follows: It is driven forward, so that one of the stalkreceivers j' will embrace each stalk ot' a row as it comes in contact with the said stalks, each stalk passing to the narrow portion of said receiver and being severed by the cutter a, working under the receiver in operation. As the stalk is cut the vibrating trame h or h (depending on the cutter' in operation) throws it upon the inclined guide n across the machine, whence it falls within thc action of the arms 1J, which convey it under the packing-guides q. As these guides pass close tothe bottom ofthe body the stalks pack under them by accumulation and cause the rear stalks to be forced backward until the body is filled. Simultaneously with the cutting ot' the stalks by the cutter c the cutters b severthe stumps from the ground and permit the passage of themachine. gathered the machine is lturned and driven across the field in the opposite direction, bring ing the other receiver j and cutter a in action to gather the next'row of corn. In this manner the operation is continued, each side of the machine being brought into operation alternately, the loads being deposited for shocking at suitable intervals.

What we claim as new and of our own inven tion, and desire to secure by Letters Patent, is-

When the stalks ot' one row are all 1. The rotary arms lo, in combination with signed oui1 names before two subscribing WitV the packing-guides g, for effecting the lling nesses. of' the body, substantially as specified.

2. The employment of a double series of cutters for' cutting stalk and stump, as described, and thereby admitting of the delivery of the 'tnesses: out product without elevation. GEO. PATTEN,

In testimony whereof we have hereunto J oHN S. HOLLINGSIIEAD.
